Abstract:

Ca phosphate (CaP) ceramics were used in orthopedics and dentistry due to their excellent biocompatibility and osseointegration. Here, the electro-assisted deposition of CaP on two different self-assembled monolayers (SAMs), 2-mercaptoacetic acid (MAA) and 2-mercaptoethanol (ME), was studied both at short (up to 3 min) and long (2 h) deposition periods on well-defined evapd. Au surfaces. The end group of the monolayer has a major effect on the growth of the CaP coating. The deposition was slower and less elec. efficient on MAA SAM, but surface cracking was essentially eliminated due to redn. of the crystallog. mismatch. The carboxylic acid may facilitate CaP growth by attracting Ca2+ ions to the surface, which could explain the higher amt. of side reactions occurring at the beginning of the deposition.
